Abstract
An apparatus for minimizing trauma to a medical fluid while transporting the medical fluid from a surgical wound by reducing the air to fluid interface during transport. The apparatus includes a suction wand for collecting medical fluid and tubing for transporting the medical fluid to a reservoir. The reservoir repeatedly accumulates the medical fluid and discharges it in a bolus when a predetermined volume is achieved. The reservoir comprises a fluid inlet, a fluid outlet, and a gas outlet. A siphon is disposed inside the reservoir for removing the bolus of medical fluid once the predetermined fluid volume is accumulated. The siphon includes a first end for suctioning the medical fluid and a second end exiting the reservoir through the fluid outlet, thereby defining an external siphon length. A pump is attached to the second siphon end to provide suction to the system. A bypass line connects the reservoir, from its gas outlet, to the external siphon length thereby removing air from the reservoir and, thus, increasing the reduction of the air to fluid interface during transport of the medical fluid.
